1. What did you do during the summer vacation?
2. What did you do during summer vacation?
(Which one is correct, #1 or #2?)
Both are correct, but # 2 is used more often.
What about the following?
1. on (the) summer vacation.
2. over (the) summer vacation
(Are both all correct?)
Grammatically, all are correct, but with the word "the" included, the sentences would read awkwardly. Better to omit "the."
